First Place: Selfie ... Cephie

These eight-armed cephalopods are quite the multitasker. No other animals are capable of such extreme arm flexibility and control. Octopuses have eight flexible appendages that can bend, shorten, elongate and twist in all directions due to their extensive nervous system and the complex arrangement of their arm musculature, which lack bones. The combination of these arm deformations creates different behaviors that can occur on one or more arms simultaneously, resulting in complex whole animal behaviors. Details from a recent study showed that all eight arms are capable of all arm behaviors; however, front arms were used more often for exploratory behaviors and back arms were used more often for behaviors involved in locomotion. Researchers recorded and analyzed a large catalog of octopus behavior from 25 octopuses across six field sites. Scientific SCUBA divers held their cameras close as the octopus tried to take a “cephie,” or octopus selfie.
